Or, the XDMF viewer can be built on top of the HDF5 viewer already there. In that case, the heavy data will be written using the HDF5 viewer and then there would be code to write the XML data in the XDMF format. This is the approach we use in our code -- we write the HDF5 files using the HDF5 API, then write with standard IO the XML file. </div>
